The European FP7 project DIANA has performed a coherent analysis of a largeset of observations from protoplanetary disks by means of thermo-chemical diskmodels. The collected data include extinction-corrected stellar UV and X-rayinput spectra (as seen by the disk), photometric fluxes, low and highresolution spectra, interferometric data, emission line fluxes, line velocityprofiles and line maps. We define and apply a standardized modelling procedureto simultaneously fit all these data by state-of-the-art modelling codes(ProDiMo, MCFOST, MCMax) which solve the continuum and line radiative transfer,disk chemistry, and the heating & cooling balance for both the gas and thedust. We allow for up to two radial disk zones to obtain our best-fittingmodels that have about 20 free parameters. This approach is novel and unique inits completeness and level of consistency. In this paper, we present theresults from pure SED fitting for 27 objects and from the all inclusiveDIANA-standard models for 14 objects. We fit most infrared to millimeteremission line fluxes within a factor better than 3, simultaneously with SED,PAH features and radial brightness profiles extracted from images at variouswavelengths. Our analysis shows a number of Herbig Ae and T Tauri stars withvery cold and massive outer disks which are situated at least partly in theshadow of a tall and gas-rich inner disk. The disk masses derived are often inexcess to previously published values, since these disks are partiallyoptically thick even at millimeter wavelength and so cold that they emit lessthan in the Rayleigh-Jeans limit. Some line observations cannot be reproducedby the models, probably caused by foreground cloud absorption or objectvariability. Our data collection, the fitted physical disk parameters as wellas the full model output are available at an online database(http://www.univie.ac.at/diana).
